hi all I have _2_ nics on my ubuntu server, eth0 for private ip and eth1 for public ip, and a loopback nic which is localhost, according to the guide below: > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI. See into your data and find answers that matter with enterprise solutions designed to help you build, observe, and protect. Try Elasticsearch free today. there are mainly three settings for networking: network.bind\_host for bind network.publish\_host for communicate network.host for above all default binds itself to the 0.0.0.0 address, and I start the es without changing the net config using wrappers: _root@es:~# /etc/init.d/elasticsearch start_ Starting Elasticsearch...
